A mathematical closed-form solution is presented for steady-state lateral response of earth and rockfill dams in canyons subjected to asynchronous excitation consisting of SH waves incident at an arbitrary angle. The dam ...

Two analytical closed-form solutions are developed for steady-state lateral response of earth and rockfill dams built in semi-elliptical canyons. In the first model, the canyon is assumed to be rigid, while the dam is ...

Significant reduction in vibration can be obtained by using semi-active control in structures subjected to pulse type excitations. This can be achieved by (a) independently variable stiffness control; (b) independently ...

The response of single-degree-of-freedom elastoplastic systems of the "slip type" is investigated for various ground motions, and the results compared with those obtained for linear systems and for conventional elastoplastic ...

A continuous flow stirred tank reactor was simulated on an analog computer. Variations in the outlet concentration of a desired product were observed as the input temperature was sinusoidally disturbed about an optimal ...

The response of coastal systems to global change is currently not well understood. To understand current patterns and predict future trends, we establish a geologic record of coastal change along the Gulf of Mexico coast.
A ...

Experiments were conducted to determine the survivability of Littorina irrorata and L. lineolata under various conditions of water temperature and salinity, and to determine the sodium and potassium ion concentrations in ...

Investigations were conducted on the littoral euryhaline molluso Siphonaria pectinata Linnaeus which inhabits the granite jetties near Galveston, Texas, Animals were subjected to a wide range of salinities, and the ...

The nuclear medicine physician uses visual interpretation of a movie-like display of the beating human heart to detect wall motion abnormalities which might be related to impaired cardiac function. The present work is ...

The invasive Chinese tallow tree (Sapium sebiferum) is difficult to control because of its large seed bank and ability to resprout from cut stumps. I performed laboratory and field experiments to evaluate the effectiveness ...

The k-restricted 2-factor problem is that of finding a spanning subgraph consisting of disjoint cycles with no cycle of length less than or equal to k. It is a generalization of the well known Hamilton cycle problem and ...

Although The Political Unconscious is an effective advocate of "the perspectives of Marxism as necessary preconditions for adequate literary comprehension" (75), Fredric Jameson's method of interpretation suffers from a ...

Traditionally, image compression algorithms, such as JPEG, have been designed for human viewers' satisfaction. Increasingly however, more and more images are being viewed by computers, for performing computer vision tasks ...

Researchers have proposed that semantic processing involves both stored semantic knowledge and mechanisms used to access and manipulate this knowledge. Support for this distinction has come from a contrast of the patterns ...

The future of computing is in allowing our devices to see what we see: Continuous mobile vision. Wearable systems will continuously interpret vision data for real-time analytics for rich context-awareness. Unfortunately, ...

The majority of standard solo repertoire that violists perform was written in the twentieth century, but the pedagogical materials violists study are largely transcriptions of violin etudes, studies, and scales, which were ...

Artificial Neural Networks have been developed at Rice University for the forecasting of the Dst index from solar wind and Dst parameters. The one hour Dst index is an Earth based measurement of variations in the H-component ...

High-resolution geophysical and geologic data were acquired in western and central Ross Sea, Antarctica, to determine the: (1) maximum extent and configuration of the ice sheet during the Last Glacial Maximum (LGM); (2) ...
